i am using Debian GNU/Linux testing, GNOME.

every package from flathub that uses GTK 3 displays text with subpixel antialiasing, while the system antialiasing is set to grayscale in dconf (the default).

users of other distros don't report this error.

subpixel antialiasing, while the system antialiasing is set to
grayscale in dconf (the default).

This is because subpixel rendering was enabled by default in fontconfig
2.14.1. And it overrides the GNOME setting (which is accessible in
GNOME Tweaks or directly in the gsettings/dconf database).

As a workaround, you can run “dpkg-reconfigure fontconfig-config” and
disable subpixel rendering (3rd question).

Sorry I overlooked that you were specifically talking about flatpaks.
My statement applies to regular GTK/GNOME applications, probably not to
flatpak which have their own runtime.
